The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

Neutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition
whose observation would have fundamental implications for neutrino physics, theories …

The Review summarizes much of particle physics and cosmology. Using data from previous
editions, plus 2,873 new measurements from 758 papers, we list, evaluate, and average …

Since the discovery of neutrino oscillations, we know that neutrinos have non-zero mass.
However, the absolute neutrino-mass scale remains unknown. Here we report the upper …

The GERmanium Detector Array (GERDA) experiment searched for the lepton-number-
violating neutrinoless double-β (0 ν β β) decay of Ge 76, whose discovery would have far …

A bstract We present an updated global fit of neutrino oscillation data in the simplest three-
neutrino framework. In the present study we include up-to-date analyses from a number of …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

Advances in machine learning methods provide tools that have broad applicability in
scientific research. These techniques are being applied across the diversity of nuclear …

Compelling experimental evidence suggests the existence of new physics beyond the well-
established and tested standard model of particle physics. Various current and upcoming …

In the current 3 ν paradigm, neutrino flavor oscillations probe three mixing angles (θ 12, θ
23, θ 13), one CP-violating phase δ, and two independent differences between the squared …
